Ok, I've heard the Ups and Downs about a lot of subs here, but I haven't had seen a lot on Hifonics Subs, if so I missed em! Does anyone have a clue on how these things are, preferably the Atlas and Goliath. I know their amps are kinda underrated and plus the are made by the same good ol' folks who make MB Quart!! Something has to be good about em!
